Navy ranks and rates in order (lowest to highest)
The Navy uses two related but distinct terms: rank generally refers to officer titles, while rate is the Navy-specific term for an enlisted sailor's pay-grade title combined with their job specialty (their “rating”) — see the full Navy rates list for every active enlisted specialty. This page covers both tracks: 9 enlisted grades, warrant officers, and 10 commissioned officer grades.
Enlisted rates (E-1–E-9)
| Grade | Rate | Abbreviation |
|---|---|---|
| E-1 | Seaman Recruit | SR |
| E-2 | Seaman Apprentice | SA |
| E-3 | Seaman | SN |
| E-4 | Petty Officer Third Class | PO3 |
| E-5 | Petty Officer Second Class | PO2 |
| E-6 | Petty Officer First Class | PO1 |
| E-7 | Chief Petty Officer | CPO |
| E-8 | Senior Chief Petty Officer | SCPO |
| E-9 | Master Chief Petty Officer | MCPO |
E-4 and above combine the rate (Petty Officer Third/Second/First Class) with a specific rating — the sailor's job specialty, such as Machinist's Mate, Electronics Technician, or Corpsman — so a full title reads like “Machinist's Mate Second Class (MM2).” E-7 through E-9 mark a major authority shift: Chiefs, Senior Chiefs, and Master Chiefs have their own “Chiefs' Mess,” distinct khaki uniforms, and significantly more command influence than junior enlisted sailors. The single senior-most enlisted sailor, the Master Chief Petty Officer of the Navy (MCPON), advises the Chief of Naval Operations.
Warrant officer ranks (CWO2–CWO5)
The Navy's warrant officer track runs Chief Warrant Officer 2 through 5 — there is no WO1 grade. Navy warrant officers are technical specialists, typically senior Chiefs who move into a warrant billet after years of enlisted experience in their field.
Officer ranks (O-1–O-10)
| Grade | Rank | Abbreviation |
|---|---|---|
| O-1 | Ensign | ENS |
| O-2 | Lieutenant Junior Grade | LTJG |
| O-3 | Lieutenant | LT |
| O-4 | Lieutenant Commander | LCDR |
| O-5 | Commander | CDR |
| O-6 | Captain | CAPT |
| O-7 | Rear Admiral (Lower Half) | RDML |
| O-8 | Rear Admiral (Upper Half) | RADM |
| O-9 | Vice Admiral | VADM |
| O-10 | Admiral | ADM |
Four-star Admiral (O-10) is the highest rank normally held. The five-star wartime rank Fleet Admiral was last held by four officers during World War II and is not part of the Navy's standing rank structure.
How rank ties to pay
Pay grade and years of service — not the rate or rank title — set your monthly base pay. See the Navy pay chart for exact base pay by grade and time in service, or the cross-branch military pay calculator to estimate total compensation including allowances.
